I like the SplitFix and consider it a necessity for the SBA3. But I did still have the little foldy parts push in towards the end plate as I was pulling the brace into my shoulder.

I received it Tuesday but didn't make it to the range until today. I put it on my LMT MRP CQB and it worked well. The fitment to the buffer tube is similar to other Magpul offerings, a little wobble but not too much. I don't care for the QD placement so I'll end up just looping the sling through the slot. For my uses for a pistol brace, it's just about perfect.
